Mapping internal temperatures during high-rate battery applications

T. M. M. Heenan et al.

Summary: This study characterizes the temperature and mechanical strain of high-rate lithium-ion batteries using advanced synchrotron XRD methods. The results show that the discharge time and optimization strategy significantly affect the internal temperature of the battery under the same current. The temperature rise is caused by heat accumulation, which is influenced by the charging protocol and battery degradation.

Optimal cell tab design and cooling strategy for cylindrical lithium-ion batteries

Shen Li et al.

Summary: The study developed a comprehensive electro-thermal model for cylindrical lithium-ion cells, showing that increasing the number of tabs connecting the jellyroll to the base can reduce internal thermal gradient by up to 25.41%. Side cooling was found to be more effective than base cooling at removing heat, with both methods resulting in similar thermal gradients within the cell. The modeling framework created is an essential tool for energy storage system design.
